6 Pulverizers That Are Crushing It in the Marketplace

How do you break one of the toughest building materials in construction? Pulverizers.

“Concrete is a material that lasts a long time. The concrete in concrete structures often outlives the original use of the structure. That is why so many attachments have been created to the destruction of concrete,” says Stuart Galloway, President, 20/20 Show Productions, the producer of Canadian Concrete Expo. “Pulverizers use tremendous force and hard, sharp teeth to break concrete into smaller pieces.”

Here are six pulverizers that are crushing the concrete crushing market.

ShearForce Equipment’s SP30 Fixed Demolition Pulverizer

The SP30 is designed to be a reliable and powerful tool for secondary demolition and recycling of concrete. It powerfully crushes reinforced concrete with its wider jaw, exceptional closing force and short cycle times provides excellent productivity in concrete reduction and reinforced steel separation, claims the company. These pulverizers feature a speed boosting system for fast cycle times, a bolt-on replaceable one-piece solid tooth system, steel cutting blades in the throat with four usable sides, and a heavy-duty cylinder cover.

NPK’s Primary/Secondary Concrete Crushers

With the newly improved tooth configuration utilizing a high-profile center tooth and lower profile teeth on both sides of the movable jaw, NPK concrete pulverizers can be used for both primary and secondary crushing operations. Abrasion resistant, high strength, alloy steel teeth provide decreased wear and increased durability. They easily crush through reinforced concrete and cut through light steel structures, which allows material to be separated and recycled, and simultaneously, permits easier handling of material. Competitive cylinder systems need larger cylinders to equal the force developed by the more compact NPK intensifier system, claims the company. In addition, the “R” models come with full 360-degree power rotation for maximum versatility and all “A” models now utilize a bolt-on replaceable tooth plate on both sides of the jaw.

Tramac 360-Degree Rotary Crushers FP Series

As result of an advanced design and many years of experience in the demolition industry, Tramac’s FP Series are marked by its technical and technological innovations. All units are composed of the best raw materials, which makes them structurally reliable. A continuous 360-degree hydraulic rotation improves versatility. Just one attachment can be used for primary demolition (such as building demolition) and for secondary demolition (such as recycling and separating fragmentation). The replaceable tips, fitted as standard on both jaws, further increase the performance, allowing the perfect separation of reinforcing rods from concrete.

Lemac Concrete Crusher

This rugged attachment not only crushes concrete, but also cuts and removes rebar. This double act creates two recyclable products with ease. As standard, Lemac includes replaceable teeth and rebar cutters allowing easy and affordable maintenance. The Lemac Concrete Crusher uses the excavator’s bucket cylinder. The attachment’s offset pivot maximizes crushing force, claims the company, which allows for over sizing of main pivot pin and reduces any stress imposed on the stick. The main pivot features heat-treated pin, bearings, seals, and o-rings and the entire jaw structure is manufactured from quenched and tempered alloy steel 130,000-psi minimum yield, 360-440 BHN.

Kenco Concrete Pulverizer

Concrete pulverizers for excavators are essential for speedy demolition, and the Kenco Concrete Pulverizer is an ideal tool for separating concrete from rebar. The force of the jaws crunches up the concrete and cleans it off the rebar, allowing for easy separation from the rest of the rubble. The attachment requires no hydraulics for operation. The excavator’s bucket cylinder actuates the movable front jaw and crushes material against the stationary back jaw.

AMI Kraken Concrete Pulverizer

Built for durable, long-term use, the Kraken Concrete Pulverizer is fully mechanical, made with Hardox wear points and requires no auxiliary hydraulics. Available for use with a coupler or direct pin-on, the Kraken’s three over four jaw configuration provides crushing strength that pushes the broken material through the jaws for efficient productivity. By using longer teeth in the centre, breaking force is maximized at initial crush by concentrating pressure across fewer points. After first penetration, the secondary jaw teeth crumble the concrete into manageable pieces. Upgrade with the optional rebar shear, effectively slicing rebar while crushing material. Made with high grade steel, the bolt-on blades are easily replaced.
